A sump pump is a type of pump that is used for removing water that has accumulated in water collecting sump basins that are usually found in the basements of homes. Sump pumps offer an ideal solution for basement flooding that occurs as a result of having a water table that is higher that the building’s foundation.
Types of Sump Pumps
There are two types of sump pumps and they include the pedestal sump pump and the submersible sump pump. A pedestal sump pump is different from a submersible sump pump in that its motor is mounted above the sump, where it is not only more conspicuous, but also more easily serviceable. The impeller in a pedestal sump pump is also driven by a vertical extension shaft and it is housed in a scroll housing that is located at the pump’s base.
The submersible sump pump on the other hand has a motor that is entirely mounted within the sump. It is completely sealed to prevent any liquid from seeping through to the motor, which might cause an electrical short circuit.
Pros and Cons
There is always debate as to which type of sump pump is better. A pedestal sump pump usually lasts a lot longer (25 to 30 years) than a submersible sump pump. This however will depend on whether it was installed correctly and whether it is kept free of debris. A pedestal sump pump is also less expensive and easier to install and remove than a submersible sump pump. On the other hand, a submersible sump pump can only last from about 5 years to 15 years depending on whether it was installed correctly. It also costs a lot more than the pedestal sump pump but it can withstand debris without suffering any damage or clogging.
Uses/Applications
A sump pump can be used in commercial and industrial applications, as well as in domestic applications to as a solution to water table related complications in the surface soil or basements of buildings. A situation where the water table rises significantly can cause instability of the ground because of water saturation. If a sump pump is installed in such a location, the surface soil will always maintain its stability. Sump pumps are usually installed at a depth of 10 feet or more and lined with some corrugated metal pipes that contain drain holes or perforations. They can come fitted with electronic control systems and audible and visual alarms.
